Implement doubly ended linked list

Doubly linked list is a linked data structure that consists of a set of sequentially linked nodes. Each node contains two links (references to the previous and to the next node) and data. The links help to iterate the node forward and backward.

XOR-linked list allows doubly linked list to be implemented using a single link field in each node. The XOR linked list decrease the memory size compare than doubly linked list. The XOR linking has few drawbacks and it is difficult to debug using debugging tools.

Write a program to implement doubly ended linked list with all the operations.

Algorithm Explanation

Doubly linked list support insert, delete and iteration operations.

Each node contains data, link to the next node and link to the previous node. The insertion link breaks the previous and next node and link with a new node on both sides.

When to insert the node in a particular position, the doubly linked list require both previous and next node links.

Insertion and deletion may require more operations in doubly linked list and other operations are simplified in doubly linked list.
